JOSEPH DEL cozze, or scoTrA, AND ALBERT W. sonrie, vor FORTUNA, oiinironimi.

-sieimniiiennvrcn v Application led l1 anuary and ALBERT W. GoBLii, a subject of the King of Ti'aly and alcitizen of 'the United States,

resp., residing at Scotia and Fortuna, resp.,-

in the county of Humboldt and State `of California, have invented new and useful Improvements in SiO-nalin@r Devices of i b. C 7 4 which the following is a specification.

This invention relates to improvements in signaling devices and has particular reference to means for signaling When the cooling iuid of an internal combustion en# gin'efreaches a lovv point inthe' radiator, where it wouldv be dangerous to run further Without replenishing the' Water.

Another object of this 'invention Yis to produce va device of this character whichKH may be attachedv to any automobile,pwithout altering the'eonstr'uction ofthe same.

An yadditionalv object of this invention is to produce a device of this characterv which is simple in construction, cheap to manufacture and onev which is relatively' free. from complicated parts Whichfmight be easily deranged. 'f A still Y further object of this invention is to provide means whereby the escape of fluid is prevented yuntil the fluid has reached a point beneath the inlet of our device.

Other objects and advantages Will be apparent during' the course of the following description.

In the accompanying drawings forming a part of' this specification, and in Which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of our device, shown attached to an automobile radiator and to the instrument board thereof,

Figure 2 is an enlarged detail cross section showin!T the valve arrangement,

Figure 3 is a vertical cross section showing one of the Whistles located adjacent the instrument board,

Figure 4 is a detail vievv of the sliding pipe connection, and v Figure 5 is a modified form of our device shoiving the auxiliary Whistle attached to the top of the radiator.

In automobiles, it is common to have the Water evaporate from the cooling' system and in hot Weather this evaporation is eX- ceedingly rapid, with a result that often the Water reaches a boiling point and after 16,'1925. seiiai No.I asiaL '1 the 'evaporation' has taken place to a considerableextent', the engine is apt to over-.

heatfand become injured. Wefhave, therefore, devised a means whereby Whenthe' Water in the radiator evaporates toa pre'v determined point an audible signal Will be given.

for the purpose of illustration is shown In the Yaccompanying drawings i'vliereiii" a .preferred embodiment of our invention, the nu'iner-al'b designates the' ordinary-radiator ,of gan automobile and ,6 tl'ievinstriiment board, coiiiinonin many makes of antonio` Thev i'iumeral` i'epresentsrthe dash; Se- Y j cured in one side 'of the radiator, at fapoint" biles.

just Withinthe usual hood, We`secure'ai`ast} ing 8, it being iminaterialyvhether vthis/casting is connected at this erranti'pointor not',

as long as" it hasv communication With the" `point beneath interior ofthe radiator, at a the' safety Water line. Y

' By referring to Figure' V2, `itlwill'mb'e noted thatthis casting has a tubular projection 9, which is screw-threaded so `as toengage Y`the 'radiatorv 5. screenI 11 serves to 'exclude' foreignf'matter from enteringffthe f signaling device. y therein a chamber l2 Within" 'which a *ball* kfloat 13 is positioned and adapted to close the bore 14, as will be later described.

This' c'astinghas formed This ball 13 is prevented from dropping beyond a predetermined point rby a pin 16. A second ball valve 17 closes the opposite end of the bore 14 and is held in Vcontact therewith by a spring 18. This spring bears uponthe under surface of aiwhistle 19.`

vAt 21 We have shown a pipe extending from the casting 8 and communicating with the bore 14, Which-pipe may be connected to a slip pipe 22, from Which slip pipe, a pipe 23 extends to a slip joint 24, from which slip jointia pipe 26 extends toa Whistle 27. vThis Whistle is secured to a housing 2S, which is, inturn, fastened to the instrument board 6, as by bolts 29 and 31. The slip joints 22 and 24 may be conofthe pipe, as necessity demands.

A packing is shown at 32 which is tight-v7 ened by a nut 33.

The operation vof ourdevice is as folloWs Assuming that the parts are attached to an automobile and that the water level in the radiator is sufcient to cover the end of the tubular projection 9, the result Will be that Water Will enter the chamber 12 and raise the float 13 into engagement with its seat, thus preventing the escape of the Water to the bore 14. rlhis condition Will be maintained at all times, when the radiator is full.

Vhen the Water in the radiator has evaporated to a point beneath the endv of the tubular member, steam will enter the chamber 12, the ball 13 will have dropped against its pin` 14, thus permitting the steam to pass through the pipe 21, to pipe 23, to pipe 26, to Whistle 27 and as this Whistle is mounted close to the driver, he Will immediately be warned that more Water should be placed in the radiator. v

The escaping steam Will condense in the housing 28 and escape through the opening 34. Should the pipe for any reason, become clogged, the pressure then would lift the valve 17 against the tension oi?V the spring 18, which Will permit the steam to operate the Whistle 19, which is of a diil'erent tone than the Whistle 27 and should be shrill so as to lWarn the driver.

In the modiiedform shown in Figure 4, a pipe isl attached to the top of the radiator which pipe is, in turn, connected to the T 36 Vfrom Which the auxiliary Whistle, similar to that shown at 21, in Figure 1, is suspended, yThe T736 is also connected to the pipe 23..

It Will thusl be seen that We have provided a very simple device and one Which Will effectively Warn the driver When the Water condition demands attention.

It is to be understood that the form of our invention herewith shown and described is to be taken asa preferred example of the same,r and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or thel scope of the subjoined claim. Y

Having thus described our invention, we claim In a device of the character described, the combination With a radiator for an internal combustion engine, of a casting having a tubular portion secured to said radiator at a point below the normal Water-line of said radiator and communicating with the interior thereof, a chamber formed in said casting, a bouyant ball positioned in said chamber, a bore formed in said casting and adapted to be closed at one end by said bouyant ball When said chamber is filled With Water from said radiator, a second ball adapted to close the opposite end of said l bore from that closed bysaid iirst mentioned ball, spring means for retaining said second mentioned ball in closed-position, an auX- iliary Whistle secured to said casting at a point adjacent said second mentioned ball and in'such a manner that said second mentioned ball Will be positioned between saidbore .and said Whistle. a Whistle remotely located With respect tosaid casting, and a pipe for conducting pressure from said bore to said last mentioned Whistle. y Y

In testimony whereof We aiiiX our signatures.
